Updated Nov 27, 2025
Explain
Argo Workflows allows users to define multi-step workflows declaratively using YAML manifests.
Each step runs as a Kubernetes pod, allowing containerized tasks with resource isolation.
Supports DAG (Directed Acyclic Graph) and step-based workflows for complex dependencies.
Integrates natively with Kubernetes for scheduling, scaling, and resource management.
Can be used for CI/CD pipelines, data processing, machine learning workflows, and batch jobs.
Core Features
Workflow as Kubernetes custom resources
Containerized execution for each step
Support for parallel and sequential tasks
Input/output artifact management
Integration with Kubernetes RBAC, secrets, and config maps
Basic Concepts Overview
Workflow - top-level definition of a set of steps
Template - reusable step or DAG component
Step - single container task in a workflow
DAG - Directed Acyclic Graph defining dependencies between steps
Artifact - data passed between workflow steps

Frequently Asked Questions about Argo-workflows
What is Argo-workflows?
Argo Workflows is an open-source container-native workflow engine for orchestrating parallel jobs on Kubernetes. It enables defining complex workflows as Kubernetes resources using YAML.
What are the primary use cases for Argo-workflows?
Orchestrating containerized tasks with dependencies. CI/CD pipelines on Kubernetes. Data processing and ETL workflows. Machine learning model training and deployment pipelines. Batch and cron-based automated jobs
What are the strengths of Argo-workflows?
Runs entirely on Kubernetes without external dependencies. Declarative YAML manifests for reproducibility. Highly scalable and supports parallel task execution. Supports complex DAGs and loops. Integrates with Argo Events and Argo CD for full GitOps pipelines
What are the limitations of Argo-workflows?
Requires Kubernetes cluster knowledge. Not ideal for non-containerized workloads. Workflow debugging can be complex for large DAGs. Resource management depends on Kubernetes configuration. Less suitable for lightweight CI pipelines outside Kubernetes
